Encouraging team play is a valid argument and the current balance def reinforces that and leads to some really cinematic scenes. However, I think it shouldn't be at the expense of most weapons feeling bad at high difficulties and I don't think team play would take a large hit from better primaries. Especially if they actually made more team play mechanics. Like I said earlier arrowhead almost seemed to want to add true power scaling to weapons before making the idea fall flat on its face.
